File Search (using regex) renders correct results on Windows, but no results on macOS

[i-a-m-d]

• VS Code Version: 1.54.3
• OS Version: macOS 10.13.6 High Sierra

Steps to Reproduce:

1. Create a file with a bunch of text, containing the words 'excel' and 'api' in random positions
2. Close the file editor
3. Perform a File Search with the following regex: ^(?=[\s\S\n]*(excel))(?=[\s\S\n]*(api))[\s\S\n]*$
4. On the macOS version of VS Code, no files are found. On the Windows version, the regex properly matches.

Does the macOS version us a different regex engine than the Windows version?

Does this issue occur when all extensions are disabled?: Yes

This is working for me in a file of just excel\napi. Can you share the exact file or try to reduce it?

We try to do some rewriting of \n in your regex to match \r?\n and it's possible that a case isn't handled correctly.

I created this example file:

Macaroni cheese halloumi api goat.
Caerphilly hard cheese bavarian bergkase feta fromage dolcelatte slices.
Bocconcini cheeseburger when excel the cheese comes out everybody's happy halloumi.
Cheeseburger port-salut cheesecake when the cheese comes out everybody's happy.
Say cheese parmesan jarlsberg.

I search for this regex:
^(?=[\s\S\n]*(excel))(?=[\s\S\n]*(api))[\s\S\n]*$

But no results:

Any variation, big or small, same result.

Still works for me

Please do the following

• Run the command "Set log level" and change it to "Trace"
• Run the search again
• Show the search-related messages in the "Log (Window)" output panel

Also you could try deleting parts of the regex to see which part is causing it to not match

I've attached the log file here: search-error.log

dyld: Symbol not found: ____chkstk_darwin
Referenced from: /Applications/Visual Studio Code.app/Contents/Resources/app/node_modules.asar.unpacked/vscode-ripgrep/bin/rg (which was built for Mac OS X 10.15)
Expected in: /usr/lib/libSystem.B.dylib

I am on macOS 10.13.6, could that be the issue?

The regex now works, after pulling in ripgrep via Homebrew and replacing the binary in /Applications/Visual Studio Code.app/Contents/Resources/app/node_modules.asar.unpacked/vscode-ripgrep/bin.

macOS support is shown as being 10.10+ on the downloads page. So maybe the ripgrep binary needs to be replaced?

Interesting, surprised this hasn't come up before. It looks like azure devops supports 10.13, so I will move the build to that version next week.
